Question

the four angles of a parallelogram abcd are in the radio of 1:4:1:4, respectively. find all the four angles. ​

Answer 1

Explanation:

let the angle be 1x , 4x. , 1x, 4x,

4x +4x+1x+1x=360

10x=360

x=360/10x

x=36

Answer 2

Explanation:

let take x all the angles

1x+4x+1x+4x=360degree

10x=360degree

x=36

1x=36

4x=36×4=144

1x=36

4x=144
